Alaska Airlines halted flights on Sunday morning, leaving customers stuck at the airport, after a national outage that began at 3:30 a.m. Pacific time and ended at 5:15 a.m.

The airline stopped some customers from boarding flights, and gate agents weren't sure when flights would resume.

A representative for Alaska Airlines told Business Insider that the outage took place in the airline's Seattle office, impacting the operations system and causing the airline to ground flights.

The representative on Sunday morning said five flights were canceled and 27 were delayed because of the outage.

The outage likely occurred because of high winds in Seattle.

The delays and cancellations are affecting travelers heading to the annual Consumer Electrics Show in Las Vegas and the JPMorgan Healthcare conference in San Francisco, including Business Insider reporters.
